` 191s. serial To. all whom t may concern: V

Be it known that 'LCARL lV. SWANSON, a citizen of the United States, residing at lChicago, in the county ofCook and State of Illinois, 4have invented certain new and use ful Improvements in Power-Driven Washing-Machines, of which the following is a specification. v

This invention relates to improvements in power driven Washing machines and-'more particularly to drivin means, latchin means and other mechanisms associated 'Wit i the tub and a manually operable means for slmultaneously controllingsaid mechanisms. 15

vention is to provide improved means' for One of the particular objects of the inshifting the power from the tub-oscillating source of ,readily apparent, to persons skilled in the mechanism and forj'simultaneously locking Y the tub in fixed position by the instrumentality operable as a resultl of movement of the manually moved lever. 1

Another object is to so construct the gear ing and its associated controlling apparatus so as to avoid accidents and to insure. lits easy and proper action .by an unskilled operator. -Y

Still another object is to provide 'a control device by means of which the tub, which in the embodiment illustrated, is of the oscillating type, may be locked in any of a num-A ber of selected positions, after its oscillating mechanism has been disconnected from th ovver.

Other o jects of my inventionlare to generally improve and facilitate the ease and positiveness of .operation of machines of this character.

i Still other and further objects will become art', from a consideration of the specification'I when taken in conjunction with the 'draw ings, wherein :fn" .Figure l is aside elevation ,of a Washing machine embodying my invention. 1 Fig. 2 is a horizontal section, taken on line 2-*2 of Fig. 1. Fig. 3 is an enlarged ,section of the tub locking mechanism,'taken on lined-6 of Fi'. 1, showing the tub locked' in position, Fig. 4 is asimilar View showing the tub unlocked.V f

In` all the views the same reference characters are employed to indicate similar parts. 'The machine illustrated in the drawings shaft, previouslyV referred to.

. the tub drive, scribed in the ap lication to which referbar 14 near its center and merges into two diverging legs'18 and 19, connected to the front and back posts 12 and 13,`respectively. A hub 20 is provided at the juncture of the post 17 with legs 18 and 19 and serves as a bearing for the stub shaft upon which the tub oscillates. Cross members 22-22 conneet the side frames,` forming a rigid structure.

The mechanisms receive their power from the horizontal shaft 23 which extends across the lower part of the' frame. Rotatably and slidably mounted upon the shaft 23 is a gear wheel 24,' which meshes with an elongated pinion 25, carried on the inner end of a. short shaft 26 thatts journaled in a hub 27 carried by the mme. A puller 28 connected to the outer end' or' the shait'z 671s driven by the ,belt 29, from the small pulley 30 on the electric motor31. l upon a bracket 32 secured tothe front of "the fra-me, and receivesits current through.

wires 34, leading from'the switch 35, conveniently located en the post 12, and from which extends the wires 36, carrying attheir ends a, connecting plug 37 for insertion in an,

electric light fitting, or socket-- A crank arm 38 is carried on the right end of the shaft 23 and through the medium of a link 39 oscillates the tub as the shaft rotates. This portion of the apparatus, as well as others, relating` more particularly to are fully illustrated and deence has been ma e above.

An A shaped extension 40 projectsupwardly from the top bar 14 of the frame 10 and carries at its apex a vertical hub 41 on which the wringer, indicated in general, at

42, is lnounted. Since the wringer, and the apparatus 'for driving it, forms no part of this application, particular description thereof will be omitted.

The wringer driving shaft 51 extends vertically up the outer side of the frame 10 and is journaled at its upper end inside the tubular wringer post 43 and at its lower end Ln albearing 52 carried lon the cross mem-` The mechanism for driving the wringer from the shaft 51 is contained in the casing clutch teeth 94, 95.

83. The vertical shaft '51 carries at its lower end a beveled gearwheel v91 meshing with the beveled gear 92 on the hub 93, loosely mounted on ,theshaft 23. The sliding gear wheel 24 carries at opposite ends of the hub,

or engagement respectively, with the wringer driving hu 93 and a collar 96 secured to the shaft 23 and through which the `tub oscillating-mechanism is actuated. The clutch member 94 is always in engagement with the wringer driving hub, irrespective of whether the gear 24 has been slid along pinion 25 to throw the clutch end 95 into engagement with the hub The motog'lv is mountedgear 24 I have providedan annular roove 97 on its hub, for engagement by a for arm 98. The forked arm is secured on the end of the shaft or rod 99, axially slidable through a journal 100 on the end frame 10. A control rod 101 extends vertically up the outer side of the frame 10, being journaled in the hub 102, 103 on the frame. The lower end of the rod 101 carries an arm 104 with a forked end 105 engaging a pin 106 in the outer end of rod 99. otation of the rod 101 through the medium of the arm 104, slides rod l99, consequently moving rear 24 into or out of tub driving position. l'lhe upper end of the rod 101 carries a forked head 107, in which is secured, onl a horizontal in 108, an end of the operating lever 109. T e free end of the lever 109 terminates in the handle 110 and passes through a pair of yokes 111, 112, the former of which is rigidly secured to the top bai' 14 of the frame and the other of which is pivoted near its right hand end on a horizontal pin 113, carried by the yoke 111. The right hand endlooking at Fig. 4-of the yoke 112, -carries a latch 114 arranged for engagement with the notches 115 on the quadrant 11G-carried by the tub 21. The left end of the yoke 112. being the heavier, the

latch end normally tends, by effect of gravity, to ride .up into engagement with one of the notches in the quadrant to lock the tub in selected position. The yoke 111, it will be noted,'has in its bottom arm, an upstanding projection 117 so that when the lever 109- is in the position shown in Fig. 3, the tub driving clutch, then being out of engagement, the outer end of the yoke 112 islfree to drop,

throwing its inner latch end up into engagement with the notch in the quadrant A116 on the tub.

To start the tub in operation, the handle is raised, thus throwing the latch out can thenbbe dropped against the lower leg of the yokelll, which is somewhat higher than the part of said leg, 'to the right of the stop 117, and the pii'oted yoke 112 will be held in elevated position with its latch outof engagement with the quadrant. as shown in Fig. 4.

The hand lever 110, which is'conveniently' located at the front of the machine, cannotl be horizontally moved to the right into clutch engaging position as it must first be raised t0 clear the stop 117. In4 pcrformv one part of its connonnd movement in onel bernecle therein, without departing from the spirit of the invention ond within the scope of the `appended Claims.
